CuSn10 Phosphor Bronze welding wire
CuSn10 Phosphor Bronze welding wire APPLICATION
CuSn10 is intended for build-up welding on cast iron, particularly suitable for welding deep drawing sheets like body sheets. This wire filler material’s good flow characteristics allow it to be used for closing large welding gaps, especially highly recommended for furnace brazing.
Copper tin alloys for example bronze with 10-12% Sn, copper-zinc alloys, copper-tin zinc-lead alloys, cast alloys for example red bronze (Rg5; Rg7). Weld surfacing on cast iron. Particularly suitable for welding of deep drawing sheet steel (e.g. body sheets). Owing to its good flowing properties, this filler metal covers wide grooves. Particularly suitable for oven soldering.
Pulsed arc welding is recommended. Preheating of the base material is usually not required. Pulsed argon arc welding is recommended for multilayer hard facing on steel.
